The recipe calls for 2 parts borax and 2 parts washing soda, so Lenny needs a total of 2+2 = <<2+2=4>>4 parts of borax and washing soda combined.
If Lenny uses 7 cups of soap flakes, which is 1 part in the recipe, then he needs 4 parts of borax and washing soda combined, which is 4*7 = <<4*7=28>>28 cups. Answer: \boxed{28}.
